YL-823 digital pressure switch

YL-823 Intelligent Pressure Switch is an intelligent digital pressure measurement and control product that integrates pressure measurement, display, output, and control. This product is a fully electronic structure, with a front end using a pressure sensor with isolation film filling oil pressure resistance. The output signal is amplified and processed by a high-precision and low-temperature drift amplifier, sent to a high-precision A/D converter, and converted into a digital signal that can be processed by a microprocessor. The processed signal controls two switches to measure and control the pressure of the control system. This intelligent digital pressure switch is flexible to use, easy to operate, easy to debug, and safe and reliable. Widely used in industries such as hydropower, tap water, petroleum, chemical, mechanical, hydraulic, etc., to measure, display, and control the pressure of fluid media.
